So Energy tariffs, prices, reviews and other information
So Energy is a small energy supplier offering green energy plans to households in the UK. All of the electricity supplied by So Energy is from renewable sources. In August 2021, it was acquired by ESB Energy but continues to operate under its own brand.
Why choose So Energy?
So Energy started in 2015 as the quintessential small energy supplier, focusing on supplying customers through a small number of tariffs focusing on renewable energy.
It was acquired by ESB Energy during the summer of 2021. ESB became a majority shareholder by purchasing more than 75% of the company, and plans were announced for the two brands to merge under the So Energy banner. This took So Energy's customer base to 310,000 and enabled the two suppliers to continue pushing the boundaries of green energy together rather than separately.
So Energy made headlines in 2023 when it became the first supplier, in collaboration with Uswitch, to launch a fixed deal for new customers to switch to since the energy market crisis began in 2021. This deal was priced lower than the level of the energy price cap and represented the first savings customers had been able to make for two years.
So Energy is signed up to the Energy Switch Guarantee, a set of 10 commitments that energy suppliers voluntarily adhere to in an effort to provide a reliable, hassle-free switch to customers. The supplier also offers the Warm Home Discount to eligible customers.

What tariffs are offered by So Energy?
At the time of writing, So Energy offers three standard variable tariffs and one 12-month fixed tariff.
- Fixed tariffs have set unit rates and standing charges for a fixed period of time, meaning that those who sign up to them have price certainty for that time
- The standard variable tariffs have unit rates and standing charges that will change four times a year based on Ofgem's energy price cap. They differ in terms of how green their energy is and whether they’re payable by Direct Debit or not, both of which affect how much they cost.
Does So Energy charge exit fees?
So Energy does charge exit fees on its fixed tariffs in line with other energy suppliers. At the time of writing, these are set at £50 per fuel.
So Energy renewable energy
All of the electricity supplied by So Energy comes from 100% renewable sources, backed by Renewable Energy Guarantee of Origin (REGO) Certificates.
So Energy lets customers decide where their renewable energy is sourced from. Each year, So Energy customers can vote on whether they would like their energy sourced from wind, solar, hydroelectric, biomass or tidal sources. The supplier then makes agreements to source their energy according to each share of the votes, so customers know exactly where their green electricity is coming from.

There are no energy providers which are specifically similar to So Energy, though any of the smaller suppliers (i.e. those outside the big six) will have comparable tariff and product offerings.
Is So Energy going bust?
It’s very unlikely that So Energy is going bust. However, the energy market remains unpredictable and there is a certain level of risk involved with any energy supplier. If any supplier were to go bust, supply would be unaffected so its customers wouldn’t lose access to energy.
